(1*/,6+ ‡ ,QVWUXFWLRQV PDQXDO
depress the pedal (11, Fig. C): the spindle should turn anticlockwise.
4) Check to be certain the hydraulic circuit is working correctly:
- move switch lever (9, Fig. C) towards the top until the spindle arms are fully extended.
- hold the switch lever in this position (top) and check if the pressure shown on the gauge on the swivel fitting is 130 bar
If the pressure value is not within the above indicate range see the "MAINTENANCE" of this manual to solve this
problem.
If the pressure shown in the manometer, is still not within this range, DO NOT USE the tyre changer and call your
nearest NUSSBAUM Assistance Centre.
DANGER! During all operations, keep hands and other parts of the body as far as possible from moving parts of
the machine.
Necklaces, bracelets and too large clothes, can be dangerous for the operator.
WARNING!
In locking the wheel, make sure that clamps are
properly positioned on the rim, so as to prevent
the tyre from falling.
1) Take the mobile control unit to work position B.
2) Pull the tool-holder arm (14, fig. D) into the upright position.
3) Operating from the mobile control centre, move the sliding table (4,
fig. D) away from the self-centering chuck and place the wheel in vertical
position on the sliding table.
DANGER!
This operation can be extremely dangerous.
Do it manually only if you are certain you can keep
the wheel balanced.
For large and heavy tyres an adequate lifting device
must be used.
4) Continuing to operate from the mobile control centre, lift or lower the arm
in order centre the self-centering chuck (3, fig. A) relative to the rim.
5) With the jaws (22, fig. A) in the closed position, move the wheel on the
sliding table to the self-centering chuck. Operate the chuck switch (9, fig.
C) to open the self-centering chuck and lock onto the inside wheel rim.
The most convenient locking position on the rim may be selected according
to figs E/1 - E/2 - E/3 - E/4 - E/5 and E/6.
Always remember that the safest locking is on the central flange.
N.B. for rims with channel, clamp the wheel so that the channel is near the
outside of the rim (fig. E/1).
